Was used only as a reference, since texture sampling is now code generated.
Already axed in the lp-binning branch too.
This fixes the llvmpipe build after recent sampling changes.
I had this patch on my hard drive for long time. It doesn't fully
address SVGA multi-threading issues, but causes no regressions, so decided
to commit while it still applies cleanly.
Attention: merging this into master will cause issues due to recent
changes in reference counting to fix strict aliasing rules violation.
This patch removes PIPE_TEX_FILTER_ANISO.
Anisotropic filtering is enabled if and only if max_anisotropy > 1.0.
Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be
considered equivalent, and meaning to turn off anisotropic filtering.
This approach has the small drawback of eliminating the possibility of
enabling anisotropic filter on either minification or magnification
separately, which Radeon hardware seems to support, is currently
support by Gallium but not exposed to OpenGL. If this is actually
useful it could be handled by splitting max_anisotropy in two values
and adding an appropriate OpenGL extension.
NOTE: some fiddling & reformatting by keithw to get this patch to
apply. Hopefully nothing broken in the process.
A src register's index can be negative if we're doing indirect
addressing into the constant buffer. Ex: MOV OUT[1], CONST[ADDR[0].x-3]
This fixes the piglit vp-arl-neg-array.vpfp test.
Before this change we were going out of bounds of the t->constants[]
array and getting garbage that later triggered an assertion.
References to program local and enviroment parameters are put into the
unified program parameters list as PROGRAM_STATE_VAR entries which point
into the local or environment arrays. So the param_binding_type field
should be PROGRAM_STATE_VAR.
This fixes the piglit vpfp-generic vp-arl-env-array.vpfp and
vp-arl-local-array.vpfp test failures.
We need to disable constant consolidation when building an array of
constants which might be indexed indirectly.
Fixes regression in piglit vpfp-generic vp-arl-constant-array.vpfp
test caused by earlier constant consolidation patch.
